6.1 SMT-200
Description
The SMT-200 consists of two main parts. The heart of the unit is the PC/104 single board computer.
This board features a CMOS 8088 - compatible CPU operating at 9.8 MHz. This achieves a good
balance between performance and excessive power consumption / heat generation inherent in faster
processors. The other part is the SMT-200 main board. This has all the additional circuitry required to
generate test signals and transfer digitised data to the PC/104.
6.2 PC/104
Description
The PC/104 runs the SMT-200 software from the onboard Solid State Disk (SSD). New code can be
downloaded to the SSD via a PC connected to the Docking Station. The PC/104 board is highly
integrated and repairs to the card are not advised. If the card is in doubt the entire SMT-200 should be
returned to the nearest I/O SENSOR service location for repair.
